IMPROVEMENT IN GUN-LOCKS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern:

Be it known that I, N11. LOOK, of Salem, in the county of Essex, andState of Massachusetts, have invented a new and useful Improvement inGun-Locks; and I dohereby declare that the following is a 'full, clear,and exact description thereof, which will enable others skilled in theart to make and use the same, reference being "bad to the accompanyingdrawing, forming part of this specification.

This invention relates to a new and useful improvement in looks forfire-arms, whereby the arms are made safer to carry and to handle thanwith the ordinary lock; and

The invention consists in the. construction of the tumbler and dog ofthe look, as hereinafterdescribed.

The accompanying drawing. represents the inside of a gun-lockconstructed according to my invention.

' Similar letters of reference indicate corresponding parts.

A is the plate to which the operating parts of the lock are attached.

B represents the hammer.

O is the tumbler.

I) is the dog.

E is the spring.

In ordinary gun-locks there is constant liability to accident, from thefact that there is no provision to prevent a premature discharge by theaccidental raising of the hammer, or against an atcilental blowon thehammer, when the hammer is left down or in contact with the percussioncap.

the gun, thereby endangering life and limb.

It has been my study to provide a remedy for this great defect ingun-locks. To secure this object, I

An accidental blow on the hammer often explodes the cap and dischargesform a notch, f, in the tumbler, and a lip, or catch, g, on the dog, tocorrespond with the notch. \Vhen the gun is discharged, the lip or catch5/, and the notch j, engage with each other, and hold the tumbler andthe hammer firmly in position, so that nothing but direct pressure onthe trigger can affect the hammer.

The lip or catch 9 holds both ways, so that the hammer can neither bepressed down nor raised up.

The adjustment may be such that the hammer is raised a little from thecap, which affords greater security than when it is left in contact withthe cap, and this latter adjustn'ient is ,what I intend to adopt, but donot intend to confine myself exclusively thereto. The peculiar form ofthe tumbler is seen in the drawing, and requires no particulardescription.

By my arrangement, the fire-arm may be carried and handled when loaded,without the least danger from premature explosion. To cock the piece, ormove the hammer, it is absolutely necessary to draw upon the trigger.

That fruitful source of accidents and frequent cause of death, thepremature or accidental discharge of the gun, will be but seldom alludedto, if my improvement is adopted.

Having thus described my invention,

I claim. as new, and desire to secure by Letters Patent- The notch f,and the lip or catch g, in combination Witnesses JOHN GENTTA, Fnanors W.Bnows.
